PROBLEM TO BE SOLVED: To provide a diversity device which can select a radio wave signal having the best reception state from a plurality of radio wave signals, and can be miniaturized. SOLUTION: The diversity device is provided with: a plurality of antennas 10 for receiving radio wave signals; and a plurality of front end circuits 11a-11n for amplifying the signal level of each of the radio wave signals received by each input terminal 10, wherein the desired signal level of IF signals 16 from the front end circuits 11a-11n are set in advance. The diversity device is further provided with: a control section 14 for comparing first amplification rate in each of the front end circuits 11a-11n; and a switch 12 for selecting an IF signal 16 from any one having the smallest first amplification rate among the front end circuits 11a-11n on the basis of a comparison result of the control section 14.
